The Seppeltsfield Centennial Collection is believed to be the world's only unbroken lineage of single vintage wines spanning more than 145 consecutive vintages. Hand bottled and exquisitely presented in a Jarrah timber gift box as a limited edition gift, each vintage from the Seppeltsfield Centennial Collection is certified for authenticity with an individual bottle number and gift certificate. The very finest parcels of Grenache and Shiraz are selected each year from the Seppeltsfield estate vineyards and reserved for the crafting of the 100 Year Old Tawny. The wine is fortified with Brandy spirit and directed to old oak barrels to rest within the renowned Centennial Cellar. Topping barrels are used to keep a dedicated 100 Year Old barrel as full as possible as it evaporates over time. The wine is then progressively transferred into smaller barrels as it continues to evaporate and build in concentration. An estimated 3% is lost each year to the angel's share, with the wine continually concentrating in flavour, aroma and viscosity during its maturation in the barrel.
